In a further improvement, the outer side surface of the shell extends outwards around the circumferential direction of the shell to form a plurality of radiating fins.

In a further improvement, the radiating fins are wavy, and the wavy directions of the two adjacent radiating fins are opposite.

In a further improvement, the lower surface of the sun shade is coated with a thermal barrier coating.

In a further improvement, the connecting rod is provided with a plurality of vent holes.

In a further improvement, the ventilation holes are provided with dust screens.

By adopting the technical scheme, the beneficial effects of the utility model are that: the utility model discloses a set up the LED lamp in the front of reflection of light note, the front of reflection of light note is equipped with the dull polish layer, and because the cavity is the hemisphere, the partial light that the LED lamp sent shines outward after the dull polish layer multi-angle refraction on the reflection of light note, is favorable to eliminating the light blackspot, makes light more even and bright, under the condition that possess the same lumen, the utility model discloses a power is far less than the power of traditional fluorescent tube, has obvious energy-conserving effect of reducing consumption; meanwhile, the sun shade is arranged, so that direct irradiation of sunlight to the connecting rod can be avoided, the storage battery assembly and the circuit board arranged in the connecting rod are in a relatively cool environment, the energy consumption is reduced, and the service lives of the storage battery assembly and the circuit board are prolonged; furthermore, by arranging the radiating fins, heat generated by the LED lamp during working can be diffused in time, the luminous efficiency of the LED lamp is improved, the power consumption of the LED lamp is reduced, and the service life of the LED lamp is prolonged; furthermore, the radiating fins are wavy, so that the radiating area of the radiating fins is increased on the basis of not changing the overall specification and volume of the lamp, and the radiating effect of the lamp is further improved; furthermore, the heat absorbed by the sun shade is reduced from diffusing to the connecting rod by coating the heat-insulating coating on the lower surface of the sun shade; furthermore, the vent holes are formed in the connecting rod, so that heat generated by the storage battery assembly during working can be timely dissipated, the conversion rate of electric energy is improved, and the service life of the storage battery is prolonged; furthermore, through establishing the dust screen, avoid the dust to get into the connecting rod through the ventilation hole and hold the intracavity.
